The Incredible Life of The Great Barrier Reef

Sea turtles

The most commonly sighted species of sea turtles that nest throughout this southern section of the Great Barrier Reef include the Green Turtle (Chelonia mydas) and the Loggerhead Turtle (Caretta caretta).

Throughout the year sea turtles will share the waters with you and can be seen whilst snorkeling or diving. From October to March each year a breeding population migrates to this region to mate and nest and turtle hatchlings can be seen making their way to the sea.


Heron Island is a very special place, where you can see Humpback whales Imigrating north from June to September each year.

Humpback whales undertake the longest documented migration of any individual mammal, with one record being over 8000 km! They essentially make north-south migrations between cold water feeding areas for summer and temperate to tropical breeding areas for winter.

They spend the winter months in our waters and the summer months in Antarctica.


The most common rays seen around Heron Reef are the Giant Shovel-nosed Ray, the White-spotted Eagle Ray, the Blue-spotted Fantail Ray, the Cow-tail Ray and the Pink-whip Tail Ray. Also seen seasonally is the magnificent Manta Ray.


The most commonly sighted sharks on Heron Reef are the Blacktip and Whitetip Reef Sharks. Both of these sharks avoid humans and are harmless if left alone.
Please don’t disturb them in their natural habitat.
